Benoy Antony commented on HDFS-6595:
------------------------------------

Thanks @jnp.  I have tested this manually by increasing the number of 
concurrent moves on the balancer side. I can add a unit test to the same, but I 
would need to change the _Balancer_ code also so that it allows to more than 5 
concurrent moves per datanode. 

> Configure the maximum threads allowed for balancing on datanodes

> Currently datanode allows a max of 5 threads to be used for balancing.
> In some cases, , it may make sense to use a different number of threads to 
> the purpose of moving.
